Wrinkle-free reduced graphene oxide (rGO)/TiO(2) hybrid multilayer films were directly fabricated using an rGO solution stabilized by a TiO(2) precursor sol applied over a large area by an air spraying method without the use of additional reduction processes. In-situ insertion of the TiO(2) layer between rGO sheets dramatically increased the conductivity and carrier mobility despite the insulating properties of amorphous TiO(2). The TiO(2) situated between rGO sheets also induced significant… CONTINUE READING
